  • What is membrane potential?
    The electrical difference across a cell membrane.
  • What unit is used to measure membrane potential?
    Membrane potential is measured in millivolts (mV).
  • What is the typical resting membrane potential value?
    The resting membrane potential is about −70 mV.
  • Why is the inside of the membrane negative?
    Because of unequal ion distribution and membrane permeability differences.
